Help A3 to S3

[Thomson_adam]

Hello guys
Recently picked up my early 2008 a3 2.0tdi s line

Since looking around the forums I have decided I want it to have more of an S3 look.

I was wondering if anyone knows of parts for sale ?
I have seen a set of side skirts on eBay as mine doesn't have any at all , they are genuine s3 skirts but it is Litteraly just the skirts , i have read on the forum about "blades" ? Is that the part that sits inside the door ? Do I have to get those too ?

As for the rear bumper . Can I buy just a diffuser or do I need to get a full new bumper ?
